I'm really desperate for an answer to this question...

Failing that, can I use physical IRQ's in a HVM domain to bind to? Eg
nothing is using IRQ 26, can I use that with bind_pirq? The only docs I
can find says 'Furthermore the calling domain must be sufficiently
privileged.', but I'm not sure how privileged 'sufficiently' means in
this context.
